I’m using the HP Reverb G2 controllers with the Windows Mixed Reality runtime to test the
XR_EXT_hand_tracking extension. I noticed the wrist joint (
XR_HAND_JOINT_WRIST_EXT) for the left hand is upside down (rotated 180 degrees about the Z axis). All the other joints and the wrist joint on the right hand look correct. I tested the same controllers with the SteamVR runtime, and the wrist joint on the left hand shows up correctly. I’ve also tested my implementation with the Oculus and Varjo runtimes with no issues.
Is this a known problem with the WMR runtime?
